I like On1 because it does all the adjustments manually but has some AI presets if you want them. The AI nose removal is very good in that you have sliders to prevent too much sharpening and noise removal - something you see far too much of in images these days. Possibly marginally less as good as DXO but more controllable than the DXO version I tried, better than Topaz and much cheaper and better value I think for what you get.
